It all started with dancing goats. Legend has it that ethiopian shepherds
first noticed the effects of caffeine when they saw their goats appearing to
become frisky and "dance" after eating coffee berries.

Once shipped, the beans are roasted at around 500 degrees Ferenheit.
After a few minutes the bean will "pop" and double in size. A few minutes
later the bean will "pop" once more. The second pop means the bean is
done.

How it works: In your brain theres something called Adenosine and it only
wants to hang out with certain receptors. When these to get together, you
get drowsy. When caffeine shows up, it attaches to the receptors so that
Adenosine cannot. Your pituitary gland sees this and thinks there's an
emergency so it tells the adrenal glands to produce adrenaline. In addition,
caffeine bumps up your dopamine levels. The result, a caffeine high.
